Patented Aug. 4, 1953 COPYHOLDER John Toggenburger, Hartford, Conn., assignor to Underwood Corporation, New York, N. Y., a corporation of Delaware Application December 14, 1949, Serial No. 132,973 l (Cl. 12B-32) 13 Claims.

This invention relates to copyholders and with regard to certain more specific features thereof to copyholders which accommodate copy sheets of much greater width than the general width of the copyholder. Such copyholders comprise open-ended sheet-curling guide means, and reference is made to the U. S. Patent to Caldwell, No. 216,654 as an example of such a copyholder.

A general object of the invention is to provide an improved device of the class indicated which is capable of manufacture at low cost, is efficient and easy `to operate, requires a minimum of storage space, and is pleasing and artistic in appearance.

It is another object of the invention to provide a copyholder of the type stated, which rising above a sheet-receiving throat has a wall that constitutes a vital part of the sheet-curling de vice, and which wall at the same time serves as a,

back rest for a copy sheet emerging upwardly from said throat.

Another object of the invention is to provide a scroll-type copyholder embodying a sheet-curling devicehaving a transverse sheet-receiving duct or pocket of generally elliptic, that is cylindroid form, the wider axis of the pocket being substantially upright and said curling device having a transverse sheet-receiving mouth or throat at the front, near the bottom, a front part of said sheetcurling device forming a back rest wall for the copy sheet emerging upwardly from said mouth. A cylindroid is defined in Websters Dictionary to constitute a cylinder with elliptic right sections.

It is a further object of the invention to provide a copyholder embodying a scroll-like sheet-curling device of generally elliptic, that is cylindroid form which affords, by reason of its form and disposition, above a sheet-receiving throat, an ex` tensive paper rest above said throat.

Another object is to provide a sheet-curling member of preferably elliptic, 'that is cylindroid appearance which is capable of fore-and-aft displacement relatively to feed roll means, thereby at times to provide an open throat for reception of a copy sheet, and at other times to render said feed roll means operable for sheet-feeding action.

It is also an object of the invention to provide simple, efficient sheet-feeding means in copyholders of the general type to which the invention relates.

A further object is to provide in combination with a scroll-like copyholder, feed roll means at the front of a sheet-receiving throat for simplicity of control and manipulation.

A still further object is to contrive eflicient means for moving said sheet-curling member relatively into and out of engagement with said feed roll means.

Another object is to provide in a scroll-type copyholder, an elongate line-finding element which can vbe easily removed for compact storage of the copyholder, or for substitution of different lengths of such elements.

A further object is to provide the line-finding element in the form of a self-straightening, fiex'- ible strip, which can be bent against the sides of the main body of the copyholder for compact storage of such copyholder. a

A still further object is to provide eicient, simple means to guide a sheet emerging upwardly from a throat of a sheet-curling guide in an arc extending in a wide sweep over the top to `the rear of the sheet-curling guide, said guide means in eiect constituting a sheet-curling guide exterior to the iirst mentioned sheet-curling guide.

Other objects and features will become apparent from a reading of the following detailed description and the accompanying drawings.

Finally, Figure 10 is a side elevation of the 3 opyholder on a somewhat reduced scale, showing such holder supporting a stenographers notebook.

Referring now to the drawings, the copyholder of the invention comprises a sheet-curling member generally designated by the numeral 2|, rising from a base l5. The base l5 is preferably molded or cast' of metal, plastic orother-suitable material. The underside of the base is flat and has cemented or otherwise secured thereto a cushion le of felt or other soft material for rest on a ta'ble. Said base lil is shallow at the rear, but rises at the forward portion to form an upreaching housing Il having sidewalls" t8', .and a front wall i9, a feed roll unit 2li being accorn-' moda-ted between said side walls in a manner to be described later. l' I A l Accommodated or nested in a niche formed behind said housing il at the shallow rearportion of base I5 is the sheet-curlinguor scroll member 2|. This curling member 2| simulates a transversely extending, open-ended'tubular elee ment of distinctly elliptic, that is cylindroid form and may be bent, molded or formed from anyv suitable material, for example Ait may be bent of stainless sheet steel. Said elliptic curling `member stands larger diameter upreaching and slightly til-ted rearwardly, and a laterally open throat or mouth 2| thereof leads near the botm tom of theY copyholder base I5 downwardly and rearwardly into the elliptic" interior of the curling member. A sheet 23 to be copiedI is introduced and pushed downwardly into saidthroat 2|', and by contact with the elliptic interior of the member 2| will curl therein as shown in Figure 2, the top edgeI of the sheet 23 being' left to protrude out of the throat 2|', above feed rolls or tires 2d constituting part of the feed roll unit 2li. Obviously, since the-curlingy member 2l and its throat are open at each lateral end, the curling member does not restrict the copyholder for use of any particular width of sheet. The interior of thecurling member 2| is very smooth and preferably polished so thatthe sheet will curl therein about with a minimum of resistance. y Said curling'-member 2| is associated with the base l5 to pivot `on an axis which extends below vvand horizontally parallel' to the sheet/#introducing mouth or throat 2|', and maybe tilted into feeding contact with the rolls 2|l as illustrated in Figure 3, or may be tilted rearwardly from said rolls tothe position seenin Figure* 2,` to leave a wide sheeteintroducing'space at the throat 27|". When the curling member 2|, as shown in Figure 3' is in feeding contact with the 'rolls 2t', the latter, due -to the frictional contact with the front side of an introduced sheet 23, when rotatedv will feed such sheet. The front side of the curling member 2| at the `general location of the feedr'olls 2|l is. h iig'hly polished for the `sheet to glide thereover upwardlywith little frictional resistance. y y

In view of the statedsh'ape 'and disposition of the curling member 2|, the front :side thereof rises relatively to great height inv a flat curve up war'dly from the feed roll unit 20, whereby there is provided a 'high-reaching, ei'cient rear rest 22 for the paper emerging upwardly from said throat.

As has been stated, the curling member 2l' is mounted to pivot about an axis below the mouth 2 and to this end, see Figures 2, 3; and 5, it has below the mouth zlhiateraiiy rmi-aways, a stud 2t reaching forwardly anddownwardly through "a circularr perforation 25 and furtherv below through a fore-and-aft extending slot 26, said perforation and slot being provided in a bracket 21 which is formed as shown and which is fastened upon the base l5 within the housing by means of screws 28. As seen in Figures 2, 3 and 5, the stud 2li has a swivel seat on the bracket 2l at the said perforation 25 and the said fore-andaft extending slot 26 guides or restrains said stud 2d to swing in a donned plane fore-and-aft about the stated swivel seat. It will be seen that the curling member 2| not only is swingable foreandaft unitarily with the stud 24 but that it is also turnable with the pin 2!! about the longitudinal axis of the latter. However, the capacity for 'such turning is very limited in View of the provision of a short stud 3B at one side of the stud reaching downwardly from the curling mem- 'ber 2|., with some clearance, into a hole 39 of a lateral extension All? of the bracket 2l. The structure stated provides that the curling member 2| is guided for movement to and from the feed rolls En', and due to said limited capacity for turning, the pressure against the two feed rolls Zi is equalized.

The bracket portion wherein the slot 25 is provided describes a curve about the stated swivel seat and a nut 2li' at the lower end of the stud 24, in cooperation with the curved part of the bracket 2'! retains the pin 2'4 in a loose ina-nner. The said studs 25a' and :i3-may be welded, riveted', or otherwise fastened to the lower front side' of th scroll member 2|. In the'y structure shown, each is riveted to an outwardly pressed blister of the curling member to leave a smooth passage for the sheet 23.

In the position of the curling member v 2| seen in Figure 3, namely in the position wherein the same is in sheet-feeding Contact with the' feed roll unit 243, a spring '29 exerts strong forward tension on the curling member. Said spring 29 has vertically above the stud 2K oneend anchored to an outwardly projecting ear '351 of the l'curling member 2|, and the other end is hooked `to the crotch of a Y-shaped control lever 30', see particularly Figure li Opposite pins `35, laterally projecting from said lever 3U, reach into spaced, upreaeh-ing ears of the bracket?? to' aflrdftherewith pivotal support' for thev lever. About midway of the front 'wall I9 of the housing" there is provided a vertical slot or opening' 3| wherethrough the Y-sliaped lever 3B' protrud'es for manipulation by the operator to give it either the: position seen in Figures 1 and Si Or the posi-'- tion seen in Figures 2 and 10, the protruding portion of the lever 38 endingl in a finger piece vor handle 32. Said spring '29 constitutesY a' resilient link which in the position of the lever Si) seen in Figure 3 is' extended or 'stretched te abnormal length, thereby to urge the curling'l member 2| resiliently intol sheet-gripping r relation with the feed rollers 202 The vposition of the lever 30 in Figure v3 is such that the line 'of' pull of theV spring 29 isl slightly below' the pivot axis ofthe lever established by the pins'- 35i 'wherefore thev lever under the tension of the spring is retained in lower position against the bttom of th'eopenlng `3i', and wherefore the springstays active until such time as the operator deliberately moves the lever 3` upwardly.

TheA point of association of thev spring" 29f in the crotch of the lever Se is such thatf'when the latter is given a slight upward movement it will snap under thetension. of the' spring to the position seen in Figure 2; Said 'pointof associ'- ation swings upwardly well above the pivot pins 33 and sufficiently to the rear for the spring 29 to relax to its normal length, and for the curling member 2| to drop by its own weight rearwardly about the described swivel point, away from the feed rolls 20. The bottom side of the curling member ZI will then rest loosely on the base I5 and the weight of the curling member 2 I, through the spring 29, will keep the lever 3|) raised against or closely to the upper end of the wall opening 3|. Thus by moving the lever 3|) from the position seen in Figure 3 to the position seen in Figure 2, the copyholder will be conditioned for free insertion of the copy sheet down the throat 2|. Conversely, when the lever 30 is moved from the position seen in Figure 2 to that seen in Figure 3, the copyholder device will be conditioned so that turning of the feed roll unit 20 will feed an inserted copy sheet.

Referring now more specifically to Figures 1 and 6, the feed roll unit 2o may comprise an elongate, generally cylindrical main member 43, of any suitable, low-cost material, preferably molded of plastic, the outer cylindrical surface being serrated as shown, thereby permitting the unit to be rotated manually with faciilty.

The ends of said cylindrical member are of reduced diameter, each having a feed roll or tire 20 cemented thereupon or stretched thereover, and retainer ring 42, of plastic or other material being pressed endwise on each reduced diameter .end to help hold the feed roll 20 in place.

The feed roll unit 2B fits closely between the two housing walls I8, and is turnably `supported in said walls I8 by a rod 4| which extends through a center hole of the cylindrical member 43 and has pivotal bearings in perforations of said walls. Said feed roll unit 2|) is assembled upon the copyholder by placing it as a completely assembled unit between the walls I8, and then pushing the rod 4I from one side through the housing I1. So that the rod upon assembly will stay in place in the cylindrical member 43, it is given before assembly a slight bend in the midsecticn thereof, such bend causing the rod 4| to bind in the hole of the member 43.

Obviously, a defective feed roll unit 20 can be easily removed by pushing the rod 4| out by use of a slightly thinner rod. Thereupon, a repaired or new roll unit, upon placing it in position is quickly mountable in place by a re-introduction of the rod 4|.

Referring to Figure l, it will be remembered that the cylindrical member 43 between the feed tires 20 is serrated. Furthermore, it is of slightly smaller diameter than the tires. `The front wall i9 rising from the base I5 Icurves at the top toward the serrated cylinder 43 and forms a shelf wherebehind there lies a large portion of the serrated cylinder exposed for finger engagement by the operator. An operator after a little practice will be able to feed conveniently the copy sheet a required line-space distance upwardly by merely setting some fingers an appropriate distance above the stated wall-shelf and gliding such fingers forwardly'to the extent possible by said shelf.

Under ordinary conditions a sheet of paper 23 extending upwardly from the throat 2| will lie rearwardly against the rear rest 22 provided by the curling member 2|, but when there are air drafts, it is desirable to have available a means to prevent the paper from being blown forwardly. This means, in the form of the mvention illustrated, consists of one or more wire guides 45, one of which is shown in Flgures `1, 2

and .3. Such guide 45 rises from the base 5 at the back of the sheet curling member 2| in a wide arc over the top of such member and downwardly toward the throat 2|'. A sheet 23 fed upwardly from the throat 2 I after being tucked behind the front portion of the Wire guide 45, will follow the inner surface of such guide in a wide arc around the back side` of the curling member 2|. The arc of the wire shown in the drawings is sufficiently large so that a 13-inch long sheet (legal size) can be fed upwardly beyond the grip of the feed rolls 20', the leading end of a so fed sheet being then just short of reaching the lower extremity of the curling member 2|, and a sheet having reached this position being freely removable by drawing it sideways from the copyholder. To accommodate larger sheets a guide 45 describing a larger arc may be used.

Three socket holes 44 for said wire guides 45 are provided along the back portion of the base I5, see Figures 1 and '7, and an operator in accordancev with choice or conditions may place a wire guide 45 in the middle hole or may place one in each of the two holes 44 farther to the side.

Each said wire guide 45 is formed near its lower end with an enlargement 46 for abutment against the base I5. Just short of the extreme lower end the wire guide 45 has a transverse groove 41 whereinto a snap 4or detent spring 48 enters as any guide is introduced in one of the holes 44, thereby detenting such guide in place and in forwardly reaching position. Said snap spring 48 comprises a straight transverse portion 48a having inwardly bent tension supplying necks 48h. A plate secured in a recess 5I! of base I5 by means of screws 5| has an upreaching front and rear wall 52 containing said spring 48 under tension, always ready for the straight spring portion 48a to spring into the groove 41 of a wire guide 45. Thus it may be seen that by inserting the lower end -of paper guide 45 down through holes 44 in the base I5 the extreme lower tip of paper guide 45 will displace the transverse portion 48a of spring 48 forwardly, and that when the enlargement 46 engages the base I5, said spring portion 48a will snap into and will take a detenting hold in the groove 41 of the guide 45.

At this time it may be pointed out that the copyholder may be used without employing the services of the paper guides 45, in which case said guides may be removed entirely or they may be turned in the socket holes 44 to lie idly in a lateral plane as indicated in dot and dash lines in Figure 2. stated, the spring portion 48a will snap into one of two grooves 41a provided as shown in Figure 8` at right angles to the groove 41, whereby the spring then detents or holds the guide in that position.

Directing attention to Figure l0, it will be noted that the copyholder of the invention may be used to hold a stenographers notebook 51, the page to be copied, along with the underlying pages being inserted between the curling member 2| and the feed rolls 20', and the other pages being tucked down between the wire guide or guides 45 and the curling member 2|, the said `guides 45 having been turned as stated in the preceding paragraph.

For a line indicator, see particularly Figures 1, 3 and 9, there is employed an elongate bar 53 preferably consisting of a pliable self-straightening spring strip 53 having scale graduations 56,

When the wire guide 45 is turned, as

enamora To the end ofi-being self-straightening; the; strip is of bowed crossesection as: shown in Fi'guresZ and 3'. Headed. studs. or rivets: 5'4 are provided ontne walls' I3, saidl strip' 53 having for'butt-oning association with each.. stud, as seen in Figure i)5 aislot 55. In assembled condition, innennar row ends of the slots are under-thel heads of the studs 54, and wider slot portions reach outwardly onthe strip.

Inasinuch assheets to' be` copied vary greatly in width, there are supplied with each device several direrent length strips 53; any one of which maybe buttoned onto. the' studs 55. The operator simply grasps the outer ends of thestrip't tovbe attached, and ilexes or bows the same. as shown in dot andi dash lines in Figure 9 until` the enlarged` portions of the slots 55 register with the studs 56, the stripv 53 by straightening is then allowed to position or button itself as shown in theY drawings. The strips 53 being in the. form of a scale may be used for miscellaneous` measuring'purposes. It will be noted additionally that for compact storage of the copyholder,y the. line indicating strip 53 may be removed, orit may be simply flexed at each side to lie closely against the side wall IB.
